H2 receptor antagonist

H2 receptor antagonists are medications that reduce stomach acid production. They work by blocking specific receptors called H2 receptors on cells in the stomach lining, which are responsible for signaling acid release. By blocking these receptors, the medication decreases the amount of acid produced, helping to relieve conditions like heartburn, ulcers, and gastroesophageal reflux disease (GERD). Common examples include ranitidine and famotidine. These drugs are generally well-tolerated and provide effective relief for acid-related issues, improving comfort and aiding in the healing of damaged stomach tissues.
